I've cleaned up the code a bit. (Enclosed Below).

If run normally from python, it displays the window, but doesn't respond
to a button down, prints the above error message, and gets stuck in the
run loop so I have to kill the process from another terminal window.

However, I've discovered that if I run it from python under gdb, it
works properly: I can grab and move the window and on button down,
it exits the run-loop and gives me a python prompt!

Any clues ???

(gdb) run
